Thanx Micheal, that dependency was missing... I got it working and played
around with it a bit.

I understand I can return a specific pixel value in the GeoTiff by passing
lat,lon to DirectPosition2D. If the lat,lon fall inbetween pixels, does it
use nearest neighbour or does it interpolate between pixels? (Maybe
something like a distance weighted mean?)

This is fine for Aster, which I know is near North-Up orientation, but
typically I would like to return Elevation values at each pixel in the image
grid, rather moving in a lat,lon grid. This will sort out any potential
rotation or interpolation isues...

Is there a way I can return the lat, lon and pixelValues[] for any specified
pixel in the geoTiff? (i.e. passing image coordinates to return
corresponding lat,lon, etc...)

Please include as much constructor detail if the code exists rather than one
line of code (I just started with GeoTools so bear with me for a while)

Thanx!
